明晰区域绿地空间格局演变影响因子的时空异质性,有助于深刻理解宏观尺度区域绿地格局演变的内在机制.本研究综合运用地理探测器和地理加权回归模型(GWR)识别了 2000-2020年南京都市圈区域绿地格局的影响因子及其时空异质性.结果表明:1)区域绿地在前10年规模减少,景观受干扰严重,后10年规模增加,景观破碎化趋势得到缓解.2)GDP、人口密度、粮食总产量、林渔生产总值、距建成区距离、林水财政支出、省级以上自然保护地规模对区域绿地格局具有显著影响.3)影响因子的作用强度存在明显的时空差异性.其中,GDP对区域绿地格局的影响呈现先升后降趋势,人口密度、粮食生产总量、距建成区距离的影响则持续上升,且GDP与人口密度的主要影响范围逐渐转移至都市圈西部、南部和城市毗邻区,粮食生产总量和距建成区距离则对北部平原地带的影响加大;林水财政支出和省级以上自然保护地规模对区域绿地格局的积极影响力逐渐增加,且空间影响范围显著扩大.本研究结论为南京都市圈制定地域化和差别化的区域绿地保护策略提供了参考和依据.
Spatio-temporal Heterogeneity Analysis of Factors Influencing the Evolution of Regional Green Space Pattern in Nanjing Metropolitan Area
To clarify the spatial and temporal heterogeneity of the factors influencing the evolution of re-gional green space(RGS)patterns,it is crucial to have a comprehensive understanding of the underlying mechanism at the macro scale.This study used the Geographical Detector and Geographically Weighted Re-gression(GWR)models to identify the influencing factors and analyse their spatial and temporal heteroge-neity in the evolution of RGS patterns in the Nanjing metropolitan area from 2000 to 2020.The results showed that 1)The scale of RGS decreased with severe landscape disturbance in the first decade,followed by an increase in scale and mitigation of landscape fragmentation in the following decade.2)Key factors such as GDP,population density,total food production,forestry and fishery products,distance to built-up areas,forestry and water finance expenditures,and the size of nature reserves above the provincial level sig-nificantly influenced the RGS pattern.3)The intensity of the impact of these key factors showed considera-ble spatial and temporal variability.In particular,the influence of GDP on the RGS pattern initially first in-creased and then decreased,while the influence of population density,total food production,and distance from built-up areas continued to increase.The primary influence of GDP and population density gradually shifted to the western,southern and peri-urban regions of the metropolitan area,while the influence of total food production and distance from built-up areas increased in the northern plains.In addition,the positive impact of forestry and water finance expenditure and the size of nature reserves above the provincial level on the RGS pattern has gradually strengthened,with a markedly expanded spatial influence.This study can provide a reference and basis for the Nanjing metropolitan area to develop a regionalised and differentiated RGS protection strategy.
